This paper reports the results of an experimental examination of the dc and ac properties of TiO2 in single-crystalline and anodic thin-film form. The single crystal and the thin film appear to obey the same dc conductivity law Iαexp V1/2 over the range investigated. Their ac characteristics are similar as well. These results may be characteristic of the metal-insulator contact rather than of the oxide itself. Resistance switching with memory was observed in almost all films, but it could not be induced in the single crystal. No existing model is a complete success, and a more complete understanding of the structure of a metal-insulator-metal system is needed before a better model can be found.
